Incompatible hazard investigation of a cycloaliphatic epoxy resin using green analytical method

A green analytical method was applied to evaluate the incompatible hazard for 3,4-epoxycyclohexane methyl-3′4′-epoxycyclohexyl-carboxylate (EEC) mixed with its synthetic materials. During the manufacturing process, numerous accidents of human poisoning, explosion, or fire have been reported due to the chemical’s incompatible reaction. A calorimetric application and product’s analysis approach have been employed to obtain related information for the incompatible hazard investigations of chemicals. This study also used nonlinear regression analysis to establish a kinetic model. The results proved that H2SO4 can cause an abnormal curing reaction and release significant amounts of heat of the curing reaction for EEC, increasing the occurrence probability of accidents.
